Abstract: ABSTRACT OF THE DISLOSURE         The present invention relates to a process for purifying flue gases developed during the combustion of waste materials and containing solids of various compositions as well as pollutant gases and heavy metals in gaseous form, wherein the primarily solid components are removed from the flue gas in a separating system and are collected as fly ashes and wherein the flue gas is washed for the  purpose of binding the pollutant gases of the residual solids components, particularly in the slag formed in the combustion process.  It is the object of the present invention to provide a  process wherein, during flue gas purification, the gaseous heavy metal contaminants as well as the heavy metal contaminants which are present in the fly ash and in the slag in soluble form, can be removed from the flue gas purification process in the most compact form, whilst simultaneously achieving good, or even improved, initial purification of HCl, SO2. NOx.  All other residues should be returnable for further use.  The remainder of heavy metal com-ponents which are not bound in the slag are isolated from the slag by a subsequent weak acid treatment.

Abstract: PROCESS FOR THE ELECTOTHERMAL PRODUCTION OF YELLOW PHOSPHORUS       ABSTRACT OF THE DISCLOSURE      The disclosure relates to a process for removing foreign components, especially zinc, from the product cycle during the production of yellow phosphorus inside an electrothermal furnace. To this end, the disclosure provides for molten ferrophosphorus and a calcium metasilicate slag and also a dust-containing gas mixture consisting essentially of carbon monoxide and phosphorus in vapor form to be taken from the furnace charged with phosphate pellets, coke and gravel. After electrostatic separation of the dust from the gas mixture, the dust is water-treated and made into a dust suspension. Crude phosphate is granulated on a granulating means using a mixture of dust suspension and binder which preferably is a clay sus-pension. The granulated material is calcined on a sintering device and made into phosphate pellets. A portion of the molten slag taken from the electrothermal furnace is allowed to soli-dify and the solidified slag is ground. The ground slag and at least a portion of dust suspension are granulated on a granulat-ing means. The granulated slag and dust suspension are dried. It is possible for the dried granulated matter to be ground once again, to be granulated once again together with a further por-tion of dust suspension, and to be dried again. The dried and granulated matter is ultimately calcined and made into pellets.

Abstract: OPTICAL CABLE TERMINATING EQUIPMENT          Abstract of the Disclosure A cable terminating cabinet for terminating optical waveguide cables contains an array of optical waveguide connectors one side of each connector having a pigtail fiber attached to it, the pigtail fibers being spliced to waveguides of a cable terminated at the cabinet.  Waveguides terminating at the other side of the connector are taken to electro-optic units where optical signals within the fibers are converted into corresponding electrical signals.  The cabinets find application either at a central office cable terminating frame or in a test access unit at a location remote from the central office.  The connectors are mounted in a panel which is exposed when a front cover of the cabinet is removed, the panel being pivoted about a vertically orientated hinge to expose a stacked set of splice organizing trays at the rear of the cabinet. Ready access is therefore possible to both the connector panel and the splice organizing trays.  However the frontal area of the cabinet is small and, because access can be gained to both the trays and the connectors from the front of the cabinet, the cabinet can be wall mounted so saving space in a central office or test access location.                             - i -

Abstract: ABSTRACT     A special form of fluid cyclone in which the velocity energy in the exit fluid is converted into exit pressure thus permitting the device to discharge to atmospheric pressure or a higher pressure while a vacuum may exit in the central core of the vortex.  The result is achieved by use of a curved passage at the exit which starts as a coaxial space and grad-ually expands and turns outward to become a circular space between two disks.  The removal of reject material to atmospheric pressure with a vacuum at the core may be achieved by limiting the restriction in cross-section of the bottom core such that the pressure is atmospheric and allow it to leave through a space between the end of the cone and a blunt shaped surface.          The above special form of fluid cyclone operates particularly well, because of reduced energy losses, when employed in a multiple arrangement in which the tangential velocity energy of fluid entering the barrel of the individual cyclone units is created by fluid flowing at larger radius such as to create a pattern of multiple vortex flow.  The vortices are in a chamber providing a common inlet to  a  plurality of cyclone units with the vortices centering on the individual units.  The special arrangement of fluid cyclones is in a geometry similar to that of a vortex trail with an even number of units of opposing vortex direction.  The same type of arrangement; i.e. having all of the units discharge into a common chamber, leads to further energy recovery in fluid leaving the fluid cyclones.
